Abstract: The present invention relates to a protective foldable cage (100) adapted to flying drones. It comprises several ribs linked at their extremities by a ring and comprising on their length several connexion points allowing strings to join each of the adjacent ribs. The length of the string corresponds to the maximal angular shift between the first and the last ribs. The protective cage further comprises easily removable locking means adapted to maintain the ribs at predetermined relative angular position once deployed. The present invention further relates to a system comprising such a protective cage and a drone support, as well as a method of protection of flying drones.

Abstract: The disclosure is directed in part to a thrust vectoring algorithm and/or thrust vectoring controller configured to allow for control of an aircraft with a plurality of tilting rotors. Thrust vectoring is a method of controlling the aircraft by pointing the motors in the direction you need thrust, as opposed to traditional methods of flight control surfaces which deflect airflow or tilting the entire body of the aircraft. The disclosed thrust vectoring algorithm and/or thrust vectoring controller allow for the control of VTOL aircraft with a plurality of tilting rotors.

Abstract: A foldable propeller assembly (1) for an aerial vehicle. The foldable propeller assembly (1) comprises a propeller blade (2) arranged pivotably about a pivot axis (P) and a first hub element (3) arranged stationary relative to the pivot axis (P). The propeller blade (2) or the first hub element (3) comprises at least two openings (13) provided about the pivot axis (P), each opening (13) is configured for interlocking with a raised portion (12) provided on the other one of the propeller blade (2) and the first hub element (3). The at least two openings (13) extend further about the pivot axis (P) than the raised portion (12) such that the propeller blade (2) has limited play about the pivot axis (P) when an opening (13) is interlocking with the raised portion (12). A biasing element (14) is arranged about the pivot axis (P) and configured for biasing the propeller blade (2) and the first hub element (3) towards each other in an axial direction along the pivot axis (P).

Abstract: An unmanned aerial vehicle according to certain embodiments generally includes a chassis, a power supply mounted to the chassis, a control system operable to receive power from the power supply, at least one rotor operable to generate lift under control of the control system, and a winch mounted to the chassis. The winch includes a reel and a motor. The reel has a line wound thereon, the line having a free end. The reel includes a circumferential channel in which a wound portion of the line is wound onto the reel. The circumferential channel includes an inner portion, an outer portion, and a passage connecting the inner portion and the outer portion. The motor is operable to rotate the reel under control of the control system to thereby cause the line to wind onto and off of the reel, thereby causing the free end of the line to raise and lower.
